Isolation and characterization of a facultative anaerobic aniline-degrading bacterium

An aniline-degrading bacterium (designated strain AN29) was isolated from dyeing wastewater process (anaerobic baffled reactor, ABR) with the capability of utilizing aniline as sole carbon source and nitrogen source. It was identified as Pseudomonas sp. based upon the phenotypic properties and a par...

Summary:An aniline-degrading bacterium (designated strain AN29) was isolated from dyeing wastewater process (anaerobic baffled reactor, ABR) with the capability of utilizing aniline as sole carbon source and nitrogen source. It was identified as Pseudomonas sp. based upon the phenotypic properties and a partial analysis of the 16S rDNA. The strain could degrade aniline under the aerobic and anaerobic conditions, the optimal initial pH 6.5 - 8.0, a temperature of 37 degrees C, and initial aniline concentrations of 500 - 2 000 mg/L with maximum concentration of 4 000 mg/L respectively.
